Abstract

A hearing protective earplug which permits alternative push-in and roll-down modes of insertion. The earplug (100) includes a soft, smoothly contoured, resilient, homogeneous viscoelastic polymeric foam main body element (1) adapted in size and shape to be inserted into a human ear canal, and an elongate stem (10) extending rearwardly and outwardly therefrom. In one embodiment, the main body element (1) transitions into a terminal flared end portion (12) lying at the outboard end. The stem (10) is typically of such length that the free end (9) thereof extends beyond the body element (1).
